Harness's 24/7 Service Guard solution enhances application performance monitoring by employing anomaly detection instead of traditional rule-based alerting methods. This approach addresses the limitations of trend-based and standard deviation-based alerts, which often lead to false positives and missed outages due to their reliance on static rules that do not account for the dynamic nature of application data. Traditional APM tools face challenges because static rules fail to adapt to variations in trend, seasonality, and randomness within time-series data, resulting in unreliable alerts. By integrating signals from various monitoring sources without predefined rules, Harness's solution allows engineers to quickly identify and address issues, ultimately improving monitoring effectiveness and reducing unnecessary alerts.
